If you have an office with a number of computers, you may want to save all your data on one common computer, so you only have to back up one computer.

You do not need Windows server to do this. You can use any computer, although you may run into limitations on the number of connections.

You can create shared folders on this computer that everyone on the network can update.

One problem is, you may have people that save files on their desktop and in their my documents folders, even though you told them to save their files on the shared computer.

One thing you can do is change their computer settings to point their My Documents folder to the shared computer.

There is a post here with instructions on how to set My Documents to another location, including a shared network drive.
